ecotraj vs gghighlight: at a glance
What is ecotraj?
Ecological trajectory analysis builds out its cyclical branch, largely through one contributor
ecotraj analyses ecological community trajectories through multivariate space, and since 1.0.0 has carried cyclical ecological trajectory analysis (CETA) alongside the linear methods. Recent releases add convergence plotting, cycle shift arrows, correspondence and reduced major axis functions, and now trajectory averaging — most credited to a single contributor, N. Djeghri. Several older release notes are bare pointers to NEWS rather than descriptions.
What is gghighlight?
A single-purpose ggplot2 extension that has spent six years tracking ggplot2 instead of growing.
gghighlight adds one verb to ggplot2: highlight the series matching a predicate and grey out the rest, with unhighlighted_params controlling how the shadowed layer renders and calculate_per_facet deciding whether the predicate evaluates within facets. The API settled at 0.2.0; the 0.5.0 release supports ggplot2 v4.0 including its ink and paper theme elements, and finally deletes gghighlight_point() and gghighlight_line().

◆ Current state
ecotraj analyses ecological community trajectories through multivariate space, and since 1.0.0 has carried cyclical ecological trajectory analysis (CETA) alongside the linear methods. Recent releases add convergence plotting, cycle shift arrows, correspondence and reduced major axis functions, and now trajectory averaging — most credited to a single contributor, N. Djeghri. Several older release notes are bare pointers to NEWS rather than descriptions.
◆ Where it's heading
The centre of gravity has shifted to cycles. The 1.0.0 release introduced CETA and reworked the underlying data structures for it, and every release since extends the cyclical branch or teaches an existing function to handle cycle objects — trajectoryDistances now compares cycles using dates for time comparison, and averageTrajectories covers both trajectories and cycles. A dependency on the MannKendall package was dropped in favour of base cor.test, trimming the install footprint.
◆ Prediction
The pattern of teaching existing linear-trajectory functions to accept cycle objects has repeated across several releases, so further functions gaining cycle support is the most grounded expectation.
gghighlight
0.0ANALYTICS
A single-purpose ggplot2 extension that has spent six years tracking ggplot2 instead of growing.
◆ Current state
gghighlight adds one verb to ggplot2: highlight the series matching a predicate and grey out the rest, with unhighlighted_params controlling how the shadowed layer renders and calculate_per_facet deciding whether the predicate evaluates within facets. The API settled at 0.2.0; the 0.5.0 release supports ggplot2 v4.0 including its ink and paper theme elements, and finally deletes gghighlight_point() and gghighlight_line().
◆ Where it's heading
Two threads run through the history. One is a slow deprecation, from soft-deprecating the geom-specific functions at 0.1.0, to defunct at 0.3.0, to removed at 0.5.0 — a five-year removal cycle. The other is compatibility work: purrr 1.0.0, dplyr's across() deprecation, ggplot2 3.4.0, then 4.0. Genuine feature additions are rare and small, with line_label_type at 0.4.0 the last one. Note that 0.3.2's notes restate 0.3.1's n() item, so adjacent tags here overlap rather than each describing distinct work.
◆ Prediction
The next release most likely absorbs further ggplot2 4.x changes, given that is what triggered the last three. Nothing in the entries points to a new highlighting capability.

Frequently asked questions
What is the difference between ecotraj and gghighlight?
Both compete on the same themes — r-package — within Analytics. ecotraj and gghighlight are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Is ecotraj better than gghighlight?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. ecotraj and gghighlight are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
